I am troubleshooting a problem with my SSD that has been working perfectly for about 8 months now. Today, while booting my computer, that has been working fine for 8 months, I got a reboot message telling me that my SSD was not plugged in correctly.
My SSD used to be plugged into 6gbit/s SATA port (grey). I replugged it, plugged it into the second grey slot but it still didn't show up in my boot menu. So I plugged it into the blue one 3gbit/s and now it is showing up. Can someone please tell me if this will be a drastic difference in speed, and if possible how I could fix this issue? Is it the motherboard failing or what? Thanks for your time!
Disconnect all drives, and clear your motherboard's CMOS. Reconnect your SSD to the 6Gb/s port and see if that fixes your problem.
Don't forget to have your SATA port in the same mode it was when your system was working properly (hopefully that was AHCI mode).
